What effects will longer stroke/raising compression have?

Post by tb144050 »

For any/all who are interested, now and in the future:

What will happen if you run the exact same setup but with higher compression? Run richer, leaner, etc??

For example, I am running a h22 setup but I am switching out my crank and rods for f22 crank and rods bc they have longer stoke and that = higher compression. All the rest of my setup will remain the same.

I will post my experience when I get all this back from the shop and thrown back together, However, I am scared about what will happen when I first crank it up...do I need to make ANY kind of adjustment to keep it from blowing up on the first turn-over?

It will run leaner, definitely. Maybe richer on the low end.

And personally, ive always been more of a fan of milling the head or decking the block, but to each their own.

My "H" needed new rings, but then it spun a bearing. So while tearing down for the new bearing, I decided to tear down further for new rings. Since I was already that far, I decided to put in my "F" crank and rods for the heck of it.

I could also mill/deck if I wanna raise compression even more..hehe
